Bose-Fermi Mixtures in Optical Lattices
M. Centelles, M. Guilleumas, M. Barranco +2
Using mean field theory, we have studied Bose-Fermi mixtures in a one-dimensional optical lattice in the case of an attractive boson-fermion interaction. We consider that the fermi…
Critical frequency for vortex nucleation in Bose-Fermi mixtures in optical lattices
M. Guilleumas, M. Centelles, M. Barranco +2
We investigate within mean-field theory the influence of a one-dimensional optical lattice and of trapped degenerate fermions on the critical rotational frequency for vortex line c…
Dynamics of F=1 87Rb condensates at finite temperatures
Jordi Mur-Petit, Montserrat Guilleumas, Artur Polls +4
We investigate the dynamics of a F=1 spinor Bose-Einstein condensate of 87Rb atoms confined in a quasi-one-dimensional trap both at zero and at finite temperature. At zero temperat…
Vortices in Atomic Bose-Einstein Condensates in the Large Gas Parameter Region
J. K. Nilsen, J. Mur-Petit, M. Guilleumas +2
In this work we compare the results of the Gross-Pitaevskii and modified Gross-Pitaevskii equations with ab initio variational Monte Carlo calculations for Bose-Einstein condensate…
